ABSTRACT:
A method of performing a soft hand-off between a first and second satellite traveling on first and second orbiting paths with an one-dimensional active electronically scanned array includes tracking and communicating with a first satellite orbiting in a first orbiting path. A scan plane of the array is then mechanically positioned and aligned so that the scan plane intersects both the first and second orbiting paths of the first and second satellites. The array continues to track and communicate with the first satellite until the first satellite is nearing a predetermined scan limit of the active electronically scanned array. The array is then operated to scan and acquire the second satellite, and establish communications therewith. Tracking and communications with the first satellite is then discontinued.
